A dictionary which called the Hyper Dictionary uses Indo-European roots. A user-friendly side has not been improved in previous research, though various functions have so far been improved by University of Aizu undergraduate students. Because links are not yet attached to the examples, links are not attached to English words used in a semantic column for explanations, although the columns are blank, the titles of columns are displayed, and so on. These factors were improved by adding links to English words with example sentences. Links were added to reference English words in a semantic column which enables consulting a word only by a click of a mouse. As a result, conjugated forms of English words made it easier to understand them intuitively. These improvements were able to greatly increase the usability of the dictionary.
